The user-friendly system provides humidity control for split systems while allowing for space dehumidification without overcooling.

Lennox’s Humiditrol® Dehumidification System for Split Systems was the 2008 AHR Award winner in the IAQ category. The user-friendly system provides humidity control for split systems while allowing for space dehumidification without overcooling. High humidity levels, rather than room temperature, activate the dehumidification cycle to improve IAQ.

When a room or building’s humidity level exceeds the system’s setpoint, the ComfortSense™ touchscreen thermostat activates the Humiditrol feature, which works with the heating and cooling system to remove excess moisture by reheating cooled air. By reducing humidity, this patented reheat design helps control the growth of mold, mildew and dust mites, which have been linked to allergies and asthma.

Based on the award-winning Humiditrol dehumidification system originally developed for rooftop units, the new split system version is a secondary coil installed downstream of the evaporator. Now available as a field-installed accessory, the Humiditrol system is matched with 3-phase T-Class™ and S-Class™ 3- to 5-ton R-410A refrigerant split systems. Designed to work with commercial air conditioner and heat pump systems, it is capable of improving space humidity levels and outperforming conventional dehumidifiers.
